To prevent alert notifications from getting caught in the SPAM folder, go here.
Adding contacts to the address book varies for different XMPP clients (Jabber). For instance, a popular IM client PSI will require you to select “Add a contact”, then enter our email firstname.lastname@example.org.
This is necessary only in the event of active limitations on getting notifications from unauthorized users. You can check if such limitations exist by initiating a test panic with the notifications already set.
